Regression factor score predictors have the maximum factor score determinacy, that is, the maximum correlation with the corresponding factor, but they do not have the same inter-correlations as the factors. As it might be useful to compute factor score predictors that have the same inter-correlations as the factors, correlation-preserving factor…

The perfunctory use of factor scores in conjunction with regression analysis is inappropriate for many purposes. It is suggested that factoring methods are most suitable for independent variable sets when some consideration has been given to the nature of the domain, which is implied by the predictors.

In 1982, Reilly developed a 13-item scale to measure role overload. This scale has been widely used, but most studies did not assess the unidimensionality of the scale. Given the significance of unidimensionality in scale development, the current study reports a confirmatory factor analysis of the 13-item scale in two samples. Based on the…

The degree of indeterminacy of the factor score estimates is biased and can lead to erroneous conclusion regarding the nature of the results. The magnitude of this bias is illustrated and guidelines for describing factor analytic studies using factor scores are offered. (Author/PN)

Study examined models for improving prediction of single and multiple criteria. (Author)

Factor scale scores are sometimes used as weights to create composite variables representing the variables included in a factor analysis. If these composite variables are then used to predict some dependent variable, serious theoretical and methodological problems arise. This paper explores these problems and suggests strategies for circumventing…

The inter-battery factor analysis model for predictive systems appears to offer a useful formalization of these systems and provides some guides for the development of the system. (Author)

Study was designed to examine the validity of the Sixteen Personality Factor Questionnaire in predicting achievement of college sophomores majoring in Education. (Authors)

The effects of sample size, number of variables, and population value of the congruence coefficient on the sampling distribution of the congruence coefficient were examined. Sample data were generated on the basis of the common factor model, and principal axes factor analyses were performed. (Author/LMO)

The California Entry Level Test (ELT) means are used with demographic variables to predict differences among California schools and districts on subsequent reading achievement tests. Factor analyses resulted in distinct factors for each of the subtests. The validity of the ELT was very high for its intended purpose. (Author/BW)

The validity of the Rational Behavior Inventory was investigated by examining its relationship with four other measures of personality in addition to class standing and age. Results supported the validity of the measure. (JKS)

This study investigated characteristics differentiating life-long learners from low participants in learning among 195 human service professionals in southern New England. Discriminant function analysis of seven extracted factors and three demographic variables indicated significant differences distinguishing the two groups. (TJH)
